If ddms does discover Memory leakage in our program, how can we locate the specific problematic code snippet and find the problem? If you analyze the code logic from start to end, it will drive people crazy, especially when maintaining the code written by others. Here is an excellent memory analysis tool-memory analyzer tool (MAT ).MAT is an Eclipse pl
When we use the SQL Server Query analyzer to view a table, we can see such a record:
The strange thing is that the "ReceiveTime" field is clearly of the datetime type. How can it be the number "62016004?
How does SQL Server insert such numbers? Even if our program is wrong and we want to insert it into the record, we will get an exception?
We also have experience in data warehousing, which may be a BUG in the query

Overview
WHO implements the Java application without a problem? Well, let's be honest ... Code Analyzer is the only custom tool to solve this pervasive problem. In this article, Laurence Vanhelsuwé will review three commercially available Java parsers: Borland's Optimizeit suite, Quest software suite, And the Jprofiler of Ej-technologies. Now the software is such a bulky, so many facets of the guy, that there is no development tool to allow program

IntroductionAt the beginning of the compiler's work, it is to read the source code (pre-compilation is not considered), and then remove some null characters, and then match the elements with their attributes (optional ), form a lexical unit. Multiple lexical units are connected to a lexical unit sequence. Since then, this method of analyzer has been completed. It's that simple. It can be seen that finding a word is the core work of the lexical

SQL Query Analyzer is a graphical management tool that is used to write, test Transact-SQL statements, and batch processing. System administrators and developers can learn how to improve performance of query execution by executing multiple queries, viewing query results, and analyzing query plans at the same time through SQL query

This time, it mainly describes the configuration of the static analyzer
When using the SQLServerProfiler analyzer to track databases during development, especially when using some ORM frameworks for development, I want to know how the SQL statement is assembled and executed, we can only trace the code step by step. Now with SQLServerProfiler, it is much more convenient to directly track which statements have been executed.
The SQL Server Profiler analyzer is used for database
Introduction
We have already introduced the implementation of the compiler preprocessing, lexical analysis, and lexical analyzer, as well as the task and process of syntax analysis.
The input of syntax analysis is a sequence of lexical units. Then, according to the syntax representation (expansion) of the language, the finite state machine theory is used to generate an abstract syntax tree and traverse the intermediate code, namely, three address code
The lexical parser or scanner is mainly used to parse the text of a string, and then analyze the words in the text to recognize the attributes of a certain type. The first step in writing a compiler or parser is to do something like this: lexical analysis. There have been many ways to use string search, where regular expressions are used to accomplish this purpose.Example:Print ("Lexical analyzer") import collectionsimport Retoken = collections.namedt
